Special Security Keys.

supports the following vehicles using the E40 ECM:

Note: To use this Vehicle Definition File you need

We now offer support for 2017 GM vehicles. The OBD2_40 definition file has been

2017 Camaro 6.2L and the Cadillac CTS and XTS with the 3.6L V6 turbo charged
engine. As you may have heard, beginning
in 2017 GM switched to a much more robust security seed/key system and
the WinFlash OBDII program can no longer calculate the security key. With this new system you will have to obtain a security key
from us the first
time you work on an ECM. Once you get the security key for the ECM you will
be able to read and program this ECM as many times as needed. There is a $25.00 administrative fee for these security keys. We will e-mail
the security key back to you as soon as possible. We will typically respond
the same business day or the next business day depending on what time of day
we receive your order. For more information on working with these vehicle
please click here. To order a
special
security key click on the Special Security Keys
link to the left.

Note: Before
working on the 2017 vehicles you'll also need to update to the latest versions
of the OBDII Tuner and WinFlash OBDII programs. You can download the
installation programs for the updates from the
Downloads page.

OBDII
Tuner CAN Support:We are pleased to announce the availability of
updates to the OBDII Tuner and WinFlash OBDII programs to add support for the
newer CAN bus vehicles. Although officially still in beta test we are making
these updates available to all current users. As usual the program updates are
free to registered users. Support for the CAN bus vehicles does require a new
OBDII Communications Interface. This
interface is a completely new design that supports both the older J1850 vehicles
as well as the newer CAN bus vehicles. It also has a USB interface for
connecting to your PC. The cost of the Vehicle Definition Files for the new CAN
bus vehicles is the standard Vehicle Definition File price of at $79.95 each.
Three CAN bus Vehicle Definition Files are currently available; the OBD2_50
which supports the 2007 - 2008 V8 trucks, the OBD2_60 which supports the T42
transmission controller used in 2007 - 2011 vehicles with a 4-speed automatic

updates to the OBDII Tuner and WinFlash OBDII programs.

Tuner Program Updates/OBDI Tune Kits:The latest version of the Tuner (and RT Tuner)
program now supports the Moates.Net Burn1, Burn2 and AutoProm programmers
allowing you to read the stock EPROM/Memcal and to program a replacement Flash
chip directly from the Tuner program. The program automatically takes care of
the Flash chip mapping so the calibration is always programmed at the correct
address. This update has also allowed us to put together some complete tuning
packages (OBD1-Tune kits) for the GM EPROM
based OBDI vehicles providing a complete tuning solution for your vehicle much
like the LT1-Tune kits for the '94/95 LT1
cars. This kits includes the Tuner program, ECM Definition File, Burn2
Programmer, Flash memory, and required adapters.

When working with the
'94/95 LT1 cars, the update to the Tuner program allows one-button access to
reading and programming the PCM.

Windows
Vista / Windows 7:For those of you running Vista or Windows 7 on our
PCs please note that all of our software can be run under these operating
systems but the installation process is a little different. Please see our
FAQs page for more information regarding the installation
of the software under these operating systems.

LT1 Tuning Kits:We are now
offering complete tuning kits for the 1994/95 OBDI LT1 cars. These kits include
everything you'll need to tune these cars.

OBD1 USB/ALDL Cable Sets: We also offer the same high quality OBDI USB/ALDL interface
cable sets that are included in the LT1 Tuning kits separately. These cables
sets are compatible with the OBDI Tuner and WinFlash programs and are also
compatible with most scan tool and data logging programs for the OBDI GM vehicle
with the 8192 baud data stream.
